The short answer is:
Does the content answer the question?
In the examples above, your initial approach is right as you are answering the questions.
But you are over anticipating other questions you might be asked or trying to show other aspects that are not being asked of in the question when you say should you go on to say what it’s important to you or detailing a past example. The questions are not asking you to do this, so you don’t need to.
But what you can do is bring elements into your initial part of the answer that briefly reference the more full details you wondering if you should include.
For instance, with the “how are we different” question, you could choose 2 key reasons why the firm is different by its strategy/work, and then could always select a third point that is more about how you have found the firm different, and why you think that is a good thing.
For the SJ questions, a brief reference like “I have taken similar approaches when I worked at Joe Bloggs Ltd, which resulted in…..” is sufficient. You don’t need to go into a full STAR format of answer.
